The Tragedy of Richard the Third is a historical play by William Shakespeare, believed to have been written in approximately 1592. It depicts the Machiavellian rise to power and subsequent short reign of Richard III of England. The play is grouped among the histories in the First Folio and is most often classified as such. Occasionally, however, as in the quarto edition, it is termed a tragedy. Richard III concludes Shakespeare's first tetralogy (also containing Henry VI parts 1-3). It is the second longest play in the canon after Hamlet, and is the longest of the First Folio, whose version of Hamlet is shorter than its Quarto counterpart. The play is rarely performed unabridged; often, certain peripheral characters are removed entirely. In such instances extra lines are often invented or added from elsewhere in the sequence to establish the nature of characters' relationships. A further reason for abridgment is that Shakespeare assumed that his audiences would be familiar with the Henry VI plays, and frequently made indirect references to events in them, such as Richard's murder of Henry VI or the defeat of Henry's queen, Margaret. The play begins with Richard standing in "a street," describing the accession to the throne of his brother, King Edward IV of England, eldest son of the late Richard, Duke of York. Now is the winter of our discontent Made glorious summer by this sun of York; And all the clouds that lour'd upon our house In the deep bosom of the ocean buried. ("sun of York" is a punning reference to the badge of the "blazing sun," which Edward IV adopted, and "son of York," i.e., the son of the Duke of York.) Richard is an ugly hunchback who is "rudely stamp'd," "deformed, unfinish'd," and cannot "strut before a wanton ambling nymph." He responds to the anguish of his condition with an outcast's credo: "I am determined to prove a villain / And hate the idle pleasures of these days." Richard plots to have his brother Clarence, who stands before him in the line of succession, conducted to the Tower of London over a prophecy he bribed a soothsayer to finagle the suspicious King with; that "G of Edward's heirs the murderer shall be," which the king interprets as referring to George of Clarence (without realizing it actually refers to Gloucester). Richard now schemes to woo "the Lady Anne" - Anne Neville, widow of the Lancastrian Edward of Westminster, Prince of Wales. He confides to the audience: "I'll marry Warwick's youngest daughter. What, though I kill'd her husband and her father?"
